(U4 0 751? p l i. which in turn commiinicates with the ducts Be it known thatl, .DAVID-O. PAIGE, a citi- I a (Z of the valve-case. The channels g It di- 5 zen of the United States, residing at Detroit, minish in depth from their ends adjacent to county of Wayne, Stateof Michigan, have inthe duct [toward their opposite extremities, ventcdacertain newand useful'lmprovement as shown, and terminatingat points on the in Means for Controlling the Aeration of Forcircumference of the valve short of .the exmenting fort; and I declare the following to tremities of the duct 2?. The valve-case is pro- 55 be a full, clear, and exact description of the vided with an index-plate j and the valve with invention, such as will enable others skilled in an indicator-finger i traversing a scale upon 10 the art to which it appertains to make and use theindicator-plate, It will be evident that ,the same, reference being had to the accomby this means the valve may be set at any de- I panying drawings, which form a part of this siredpoint on the scale to effect any given 60 I specification. I 1 I amount of aeration which may be desired.

y invention has for itsobject means for The operation of the device is obvious. controlling the aeration of fermenting wort The channels 9 f. of the valve may be adjustin a fermenting-apparatus; and it consists of ed by the rotation of the valve, so as to enthe I construction, combination, and arrangelarge or diminish the amount of air supplied 5 nient .of devices hereinafter specified and through the valve. Inasmuch as-the channels el'aimed, and illustrated in the accompanying 'g I) diminish on th carc of the circle from the drawings, in whichtransverse duct or channel 2' in the opposite Figural is a view in plan, illustrating'fea direction, the valve may be turned to give an tnres of my invention. Fig, Q'is a view in opening varying. practically from an infini- 7 vertical section. Fig. 3 is a view in horizontesimal to a full-sized'opening. The channels talsection onthh lineBB, Fig; 2. g It being elongated enable the amount of My invention is more especially designed aeration 'eiiected to be registered upon the to be applied to the suction-pipe of a vacuurn' dial-plate 'more accurately than would be the fermentation apparatus employed 'to supply case werethere no channels y it. The ability 75 air to thefermenting wort, although 1 do not by'this construction to graduate the openings limit myself solely thereto, as my invention so closely andjregister the same is a point'of may be employed where admission of air to great importance. The graduations when the fermenting wort is effected under pressure. the device is in operation may he tested. by a In carrying out my invention as illustrated meter, soas to insure the exact number of 80 in the accompanying 'drawings;m ri'rcpresent cubic feet of aeration in a given time. This portions of pipe for supplying air to thefer" construction enables-a slight variation in "the mcnting wort, through which pipe air may quantity of air that passes through the valve he supplierhby suction or pressure, as may be to be made with a comparatively long movedesired. My improved device is interposed mcntof thel'iandleof theyalve. 1 preferthat 5 in said pipe, the same consisting, essentially each of thegraduated channels shall extend of a valve-case I), provided with channels or aboutthe valve on an arc spanning more than 40 ducts c di',-conimunicating witl the adjacent ninety degrees, by which construction it'will portions 1/. a of thesupply-pipc, respectively, be seen that the supply of air admittedthrough and with the interior of the case. A rotatablc valve is located within said case, provided with an operating-handlef. Between its extremities the periphery of the valveis formed with arc-shaped recesses or graduated l.
